Larry,
I
haven't had any "sweating" issues with my steel braided lines or fittings.
As long as you properly assemble the fittings/lines they shouldn't leak.
Ensure the ends of the fittings and internal threads are well lubricated before
putting the pieces together, and it helps to have a set of aluminum vise jaws
and aluminum a/n wrenches when you assemble the fittings.
Before
I installed the rear sump, I had a worm gear clamp to hold the braided line to
the sending unit's barb. I don't know if that was the right way to do it
or not, but it worked with no leaks.
As
Dale mentioned, the a/n fitting seals on the 37* flare, not the threads.
However, you can use Teflon tape or thread sealer on the pipe threads of the a/n
to pipe thread adapters.
Also,
the shut-off valve is a great idea to include in your fuel system, especially
when you need to disassemble a fuel line or change the filter. It's also
makes a good theft deterrent.

Herb,
Thanks for your input. I'm still learning my way
around cars after a 25 year break while serving my country and raising a
family. This is my first time working win AN type fittings...
1. As Clint mentioned, have you experienced
any "sweating" or leaking issues with AN fittings?
2. What type of fitting would I need to get to
attach the braided stainless hose to the tank sending unit's barb
fitting?
3. Would the use of teflon tape on the threads be
appropriate on fuel lines?
Thanks for your help.

Hi
Larry,
You've got the right idea going with the -8 line. Right now I
have -6 supply line from the tank (modified w/ rear sump), to the
filter, to the pump, and then -8 from the pump to the carb. However,
I'm in the process of getting the pieces to convert all the -6 to
-8. As for the filter, I originally had an inline type filter on the
frame rail by the engine mounted fuel pump but found out that any large
debris caught by an inline filter can significantly reduce fuel flow at
the worst possible time - at the drag strip! After that happened I
mounted a Fram canister style fuel filter back by the gas tank.
Also, I covered the line from the pump to the carb with Thermo tech
sleeving.

Doug,
I was thinking about running a braided hose
all the way as well. I have the same concerns you do, so I'm planning to
go with Summit p/n SUM-PUMPKIT3 which is a - 8 AN diameter fuel line kit
designed to work with 3/8 in. NPT components. That's my plan
anyways, unless somebody here can speak up and tell me I'm headed in the
wrong direction.

I am doing the same thing on 66 chevelle 400 SB 750
demon carb. I am going to run braided -6AN hose all the way and
put a filter in line. I am using -6an connectors no clamps!!
my only concern is that -6an hose is .032 smaller in dia. hope this is
not too small for my 750 carb??????

I'm getting ready to run new fuel line from
tank to my mechanical fuel pump (Holley 110gph) to carb. Any suggestions
concerning type of fuel lines to use, and what you are using to filter
your fuel and placement of filter(s) would be appreciated.
Also, is anybody out there insulating the
fuel line coming up to the carb?
Thanks,
Larry
